Hi,
I'm running BOINC ver 7.9.3 (x64) with wXwidgets ver 3.0.4 on Ubuntu 19.04 on two laptops 24/7. I also have BOINC running on a desktop running Windows 10.

I want to reduce the CPU access on both laptops which is currently set at 100 percent. When I select Options, Computing Preferences in the manager the dialogue appears but the box is empty.

Can anyone advise, please?

Ian

If you have never set preferences manually on those machines, they will still be running with web-based preferences. So you can set new values using the global "Computing preferences" page, in your account at any of the projects the machines are attached to.

Is it worth trying an update to the most recent version, (7.14.2 with 7.16 due out some time soon.) I am also on Ubuntu 19.04 and at least with the latest version all the options are there.

I'm testing out a Linux Mint 19.1 Tessa box, which also has v7.9.3 as the default repository version. All the options are visible in the dialog there, so this isn't a generic BOINC Manager problem - might be a library issue on the OP's machine?

If it is a library issue, presumably starting from a terminal should show what the problem is?
